I just made this recipe up this morning because I had an over ripe banana and some frozen blueberries. We all thought they came great. My omnivore friend came over for lunch and loved them! She even wrote down the recipe right away. I'm sure you can modify the type of flour you use, too, depending on what you have in the house.
Enjoy!
